Form of order sought

The appellants claim that the Court should:

Pleas in law and main arguments

In support of the appeal, the appellants advance two grounds of appeal.

First, the General Court erred in law by concluding that the BoA had not infringed its obligation to carry out a full review of the underlying Decision 02/2020 of ACER of 24 January 2020 on the Implementation framework for the European platform for the exchange of balancing energy from frequency restoration reserves with automatic activation. At the time of the adoption of the BoA Decision, the BoA understood its legal obligations as not mandating a full review of complex technical assessments. That understanding, which is contrary to the case law of the Court of Justice, was reflected in the explicit wording of the BoA Decision. It was not open to the General Court to reinterpret the explicit wording in the BoA Decision to conclude — in direct contradiction with that wording — that the BoA had carried out a full review.

Second, the General Court misapplied Articles 21 and 37 of the Commission Regulation (EU) 2017/2195 (1) of 23 November 2017 establishing a guideline on electricity balancing in its assessment of the legal basis for ‘required’ platform functions under Article 21. The appellants submit that the General Court committed two specific legal errors. First, contrary to the terminology and structure of the Commission Regulation 2017/2195, the General Court wrongly found that capacity management through the calculation of cross-zonal capacity is a required platform function covered by Article 21, because Article 37 requires transmission system operators (‘TSOs’) to conduct a process of continuously updating cross-zonal capacity. Second, the General Court failed to respect the distinction between legal obligations on the TSOs in performing a ‘required’ platform function under Article 21, and their rights (contained in the same provision) to propose additional platform functions.
